"Oh." Soldat blinks now, too. "The other one. Okay."

And then they... settle. That absolutely makes sense to them and isn't as much a cause for concern. Sora is talking to the guy with two people in their head, both of whom often have wildly different emotional reactions to the same set of stimuli, which are often wildly different from their own reactions. Mostly the emotions don't leak out like that... but their headspace isn't quite the same as Sora's headspace, and they understand that.

"What can we do to help," they ask. The "we" means Soldat and Sora, but could probably be taken to mean the three Soldat-pieces, too.
